MUSIC-LEAF TURNER.

Specification of Letters Patent.

Application filed December 19, 1908. Serial No. 468,313.

To all whom it may concern:

Be it known that I, NICHOLAS ARMINIO, a citizen of the United States,residing in the borough of Brooklyn, of the city of New York, in theState of New York, have invented certain new and useful Improvements inMusic-Leaf Turners, of which the following is a specification, referencebeing had to the accompanying drawings, forming a part hereof.

The object of this invention is to provide a device for turning theleaves of sheet music, etc, which shall be readily applicable to apiano, organ or music stand and shall oper ate with certainty and ease.

The invention will be more fully eX plained hereinafter with referenceto the accompanying drawings in which it is illustrated and in whichFigure l is a view in front elevation, partly broken out to save space,showing the improved music leaf turner applied to a music stand. Fig. 2is a view in front elevation of the music leaf turner on a larger scalethan Fig. l and also partly broken out.

Fig. 3 is a top view of the parts shown in Fig. 2. Fig. 4: is a detailview in section on the plane indicated by the line H of Fig. 2 with theleaf holders omitted. Fig. 5 is a partial view in front elevation ofsome of the parts shown in Fig. 2 but in a different position. Figs. 6and 7 are views in front and edge elevation respectively of a differentform of leaf holder.

For convenience in illustration of the in vention it is shown in Fig. 1of the drawings as applied to an ordinary music stand having a base aand supporting pillar 6 upon the top of which is secured a music rack c.To the latter is secured a plate (Z upon which are mounted the workingparts of the leaf turner, the actuating device being shown as a pedal 6mounted upon the base a and connected by a cord or chain or othersuitable connection 6 with the working parts of the music leaf turner.It will be obvious, however, that the plate (Z, with the parts carriedthereby, might be secured to the music rack or board of a piano ororgan, or a music stand of other character than that shown, and that anyother convenient form of actuating device might be employed and suitablyconnected to the working parts.

In the music leaf turner as shown in the drawings a shaft 7' is mountedin bearings f" secured to the plate (Z and has secured thereto one ormore springs f by which it is rotated toward the right or contrary tothe direction of movement of the hands of a watch (see Fig. 3). Looselyvmounted on the shaft f is a wheel or drum 9 to which is connected thechain or cord 6' by which the shaft may be rotated toward the left or inthe direction of the movement of the hands of a watch and in oppositionto the spring or springs F, as hereinafter explained. The wheel or drum9 also has secured thereto one or more cam pieces it, for a purposepresently to be explained. Secured to the shaft f is a broad flat arm 2'having at its extremity a lip 2" which overlies the leaf holdershereinafter referred to and furnishes a bearing surface against whicheach leaf holder may be held firmly by a finger 74 adapted to slidelongitudinally upon the arm 2' in guides 2' formed therefor. The finger7c is normally withdrawn by a spring 70 and is projected by the rotationof the cams 72, with respect to the shaft- 7, such cams bearing againstthe rear or inner end of the finger 7c and working in slot-s formedtherefor in the arm 2'. The lip 2" of the arm 2', as will be observed,is somewhat ofiset from the finger is so that there is left between thelip and the finger a space suflicient to receive the shank of the leafholder as hereinafter explained. Also secured to the plate (Z are guidesZ for the leaf holders, such guides being preferably formed by wireswhich are bent in semicircular or substantially semicircular form, butare slightly eccentric with respect to the shaft f, as clearly indicatedin Fig. 3. The leaf holders, which may be of any suitable character, aremounted on the guides Z. As shown in the drawings each leaf holdercomprises a thin fiat plate m of metal having holes 77?. for the guidesZ and having lugs m by which the plates m are held slightly apart, asshown in F 2 and 3. The edges of theplates m are also slightly beveled,as shown at m in Fig. 2, to facilitate the engagement of the finger7ttherewith. The shank of each holder carries a part to engage thecorresponding leaf.

As shown in Figs. 1 and 2 the shank has pivoted thereon, as at n, afinger n which is Patented Aug. 24., 19M).

suitably formed to underlie the leaf to be turned and to support itduring the turning movement, the finger n being pivoted so as to permitit to be turned down out of the way if desired. As shown in Figs. 6 and7 each shank m is provided with a socket m to receive the tongue 0 of aspring clip 0 which may be made to grasp the lower edge of the leaf orsheet to be turned.

In the operation of the device as shown in the drawings pressure isapplied to the pedal 6 and the tension thus created on the connection 6is transmitted first to the wheel or drum 9, which is thereby turnedupon the shaft 7', the arm i being then in its right hand position asshown in Figs. 1 l. The partial rotation of the wheel or drum 9 thuseffected causes the cam piece it to act against the rear or inner end ofthe finger 7c and to project the same to the right, as indicated in Fig.at. As the lip z" of the arm 2' then lies upon the shank of the topmostleaf holder and is slightly ofiset from the extremity of the finger 7s,and as the shank of each leaf holder is slightly separated from thenext, as shown in Fig. 3, the extremity of the finger It thereforepasses under or behind the shank of the topmost leaf holder, causingsuch shank to be held firmly and with a broad bearing between the lipand the extremity of the finger. The continued movement of theconnection 6 causes the cams to bear against the ends of the slots 2'which thus, with the cams, form stops to limit the movement of the wheelor drum with respect to the shaft, and thereafter the shaft is rotated.The rotation of the shaft causes the arm 2' to swing about the axis ofthe shaft from the position shown in Fig. 3 to the position shown inFig. 5 and this movement of the shaft carries the leaf holder over fromthe right hand position to the left hand position. By reason of theeccentricity of the guides Z the leaf holder is carried clear of the lipz" of the arm 2' as it approaches the limit of its movement toward theleft so that the arm is free to be returned to the right by the actionof the springs f of the shaft as soon as the tension of the connection 6is relieved, the finger ]t' being at the same time withdrawn by thespring .1 so that it will clear the topmost leaf holder at the rightwhen the arm reaches its right hand position. Successive operations ofthe leaf turner will, therefore, move successive leaf holders from theright hand position to the left hand position, causing successive lea-fholders to be turned from the right to the left. To return the leafholders, one or more, from the left hand position to the right handposition, the arm i is held in the left hand position with the finger 70withdrawn and the leaf holders are then moved leaves engaged by suchfrom left to right by hand. For convenience in holding the arm 2' in theleft hand position a latch 79 is mounted on the plate cl and adapted toengage a lug p on the arm 2.

It will be obvious that various changes might be made in the details ofconstruction, and arrangement of the leaf turner and the invention,therefore, is not to be limited to the precise construction shown anddescribed herein.
